Pikachu's design has changed greatly over the years.
There are a lot of other designs. Which one is your favorite? Mine is the R/G design.
I like Pikachu's ridiculously cute "Magical Pokemon Journey" design. I'm also a bigger fan of the game art than the anime art--although I do like Ash's Pikachu and his many impressions of other Pokemon.
I love the third gen pikachu artwork... Its just so cute!
I. LOVE. HIS. EPIC. ADVANCED BATTLE FORME! He was so... POWAFULL! Yet cute...
there was this baby bib which had a cute little pikachu on it.It was like a cross between the first sprite and the 3rd gen sprite.
